chore: Introduce token focus controller helper

[pan-kot]

Description

Standardise focus handling between property filter tokens, nested tokens, editor tokens, file upload, and token editor.

This also fixes a bug caused but next filter index not being cleaned up. As result, the token transition did not always happen or instead of focusing on the adjacent token the focus moved to the input, see recording:

The useListFocusController is a nice solution to the problem.
